On January 22, 2013, Mercury General Corporation (the Company) took action to consolidate its claims and underwriting
operations located outside of California into hub locations in Florida, New Jersey and Texas. The consolidation is intended to improve long-term profitability and to position the Company for future growth outside of California. The Company expects a
net workforce reduction of approximately 135 employees, representing less than 3% of the total workforce. The Company expects to record a charge, in the first quarter of 2013, of approximately $8 million to $13 million for employee termination,
employee severance and office closure costs, all of which will result in future cash expenditures. The total annualized pre-tax cost savings that are expected to result from the consolidation is estimated to be approximately $13 million.
